Adapter device for optical memory discs having a reduced size, and a promotional article comprising said adapter device

ABSTRACT

The adapter device comprises a ring of flexible material, in particular card, having an outer perimeter which at least partly corresponds to the inner perimeter which at least partly corresponds to the outer circumference of a compact disc of a size smaller than the standard size. The adapter ring is folded along predetermined fold lines in such a way that when in the folded condition it cam have dimensions which are close to or smaller than the external diameter of the compact disc.

CROSS REFERENCE TO RELATED APPLICATION

This application is a 35 U.S.C. § 371 National Phase Entry Application from PCT/IB2004/003264, filed Oct. 6, 2004, and designating the U.S.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an adapter device of the kind defined in the preamble of claim 1, which makes it possible to use an optical memory disc of the “compact-disc” type having dimensions (external diameter) smaller than a standard size or measure in a read and/or write device.

“Compact discs” have for many years predominated as high capacity memory media, initially as audio-digital media and more recently also as media for data in general.

Compact discs with the greatest variety of contents have been placed on the market for sale as separate commercial products, or as articles distributed in association with other commercial products to promote sales of the latter.

Normal compact discs are manufactured having a standard diameter of 12 cm (4.75″). Correspondingly, read-write devices have a recessed or depressed seat of precisely that standard diameter to receive these compact discs.

In addition to the principal seat having a diameter of 12 cm read-write devices generally have a further seat, which is further depressed, with a diameter of approximately 8 cm. This seat can be used to receive and locate 8 cm optical discs.

Standard read/write devices are not however able to “accept” compact discs having further reduced dimensions.

2. Description of the Related Art

An adapter device of the initially defined kind is disclosed in EP-A-0 883 126. This prior art document discloses a solution aiming at reducing the size of an adapter ring for a video game CD having a reduced size (3.25 inch rather than the standard 4.75 inch), so that such a CD and the folded adapter ring can be attached to smaller books describing the game. This aim is achieved according to EP-A-0 883 126 by an adapter ring which is folded only once, along a diametrical fold line. In this way the folded adapter ring has a reduced size, and can be attached (together with the reduced-size CD) to a smaller game description book. The size of the folded adapter ring is however not too small, so that the adapter ring and the game description book can effectively protect the CD.

US-A-2001036148 discloses another adapter ring for small-seize CDs. The adapter ring (FIG. 2A) has three radial fold lines at 120° to one another.

JP-A-10125026 and the corresponding abstract disclose an adapter ring for small diameter disks. The adapter ring has two opposite, parallel chordal portion or sides, which alternate with curved portions or sides. Said chordal portions or sides somehow involve a reduction of size of the adapter ring, which is however outbalanced by the presence of a plurality of projections which protrude radially beyond the circumference to which belong said curved portions or sides of the adapter ring.

SUMMARY OF THE INVENTION

This invention has been developed in particular, but not exclusively, with a view to allowing the distribution and use of compact discs having reduced dimensions in comparison with the abovementioned standard values, for example having a diameter of approximately 5 cm and a capacity of the order of 10 Mbyte, in particular in association, as promotional articles, with commercial products of small size, in particular food products.

The invention has in particular been developed in order to permit the insertion of such a compact disc of somewhat smaller dimensions in combination with food products, either within the packages for the latter (for example buns, ice-cream or the like), or within the food product itself (for example hollow chocolate products or the like).

This and other objects will be achieved according to the invention through an adapter device, the salient features of which are defined in the appended claim 1.

Promotional articles comprising a compact disc of reduced size and an associated adapter device according to the provisions of claims 10 et sequenter likewise constitute an object of this invention.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, 1 indicates as a whole a compact disc having an external diameter which is smaller than the standard diameter. This compact disc has for example an external diameter of 5.1 cm, an internal diameter of 1.5 cm and a thickness of 1.2 mm.

Compact discs 1 of reduced size may be manufactured for example by punching or cropping a compact disc of standard dimensions, in particular from a copy manufactured from a so-called “gold” copy.

In its simplest embodiment an adapter device essentially comprises an adapter ring such as that indicated by 2 in FIG. 2 and the subsequent figures.

Adapter ring 2 is manufactured from a flexible material, in particular cardboard, having a thickness of preferably not more than 1 mm.

In the embodiment illustrated in FIGS. 2 to 5 the adapter ring has an outer perimeter 3 which corresponds to the outer circumference of a standard compact disc, for example having a diameter of 12 cm.

Adapter ring 2 also has an inner perimeter 4 which corresponds at least partly to the outer circumference 5 of compact disc 1.

Adapter ring 2 is folded along predetermined fold lines L1, L2 (FIG. 2) in such a way that when in the folded configuration (FIG. 3) this ring 2 has a size which is similar to or smaller than the external diameter of compact disc 1 (FIG. 4).

In the embodiment illustrated adapter ring 2 is essentially folded in two diametrical directions L1, L2 substantially at right angles to each other in such a way as to form four adjacent segments interconnected at the folds.

Adapter ring 2 is unfolded for use, so that it has the planar annular configuration shown in FIG. 2.

Conveniently adapter ring 2 may be provided with adhesive reinforcing means which may be applied thereto in the unfolded operating configuration to prevent any tendency towards resilient return to the folded condition. These adhesive reinforcing means may comprise a self-stick ring (not illustrated) having dimensions which are smaller than or at the most the same as those of adapter ring 2, and which can be applied to one surface of the latter.

As an alternative, the aforesaid adhesive reinforcing means comprise a plurality of self-stick elements or tabs of small size, such as those indicated by 6 in FIG. 5, which can be applied to the fold areas of adapter ring 2, straddling the fold lines.

For use the ring and the self-stick elements are conveniently provided with corresponding peelable coatings protecting their surfaces or the self-stick side.

With reference to FIGS. 6 and 7, in an embodiment outer perimeter 3 of adapter ring 2 has a plurality of portions or sides 3 a which extend essentially along the chords of a circumference 7 having a diameter corresponding to the external diameter of a standard compact disc. The perimeter of adapter disc in FIG. 6 also has a plurality of curved portions of sides 3 b corresponding to arcs of the aforesaid circumference 7. These curved sides 3 b alternate with chordal sides 3 a. The latter are at right angles to the diametral fold directions L1, L2 in pairs.

As may be appreciated by comparing FIG. 7 with FIG. 3, the embodiment of adapter disc 2 described above with reference to FIGS. 6 and 7 makes it possible to appreciably reduce the maximum dimension presented by this adapter disc in its folded condition.

As previously stated, conveniently the maximum dimension of the adapter disc in the folded condition is close to or possibly less than the diameter of compact disc 1. This feature is advantageous having regard for example to the possibility of inserting folded adapter ring 2 in a juxtaposed relationship with a compact disc 1 either within a pack for a food product, such as a bun, an ice-cream or the like, or possibly within the food product itself, such as a hollow chocolate product and the like.

Naturally, the principle of the invention remaining the same, the forms of embodiment and details of construction may be varied widely with respect to those described and illustrated, which have been given purely by way of example, without thereby departing from the scope of the invention as defined in the attached claims.
